903 Coolant and oil capacity, gearbox and hubs

Hi Paul. work out how much coolant you need like Cam said, then buy the coolant premixed in 20l drums and fill. It used to be called complete 50.
Spin on a zero unit filter.
its a bit dearer but the guess work is taken out of it.

It looks as if Castrol Premium Cool Plus 50 is direct equivalent to the Fleetguard Compete 50, same test kits, loaded with SCA for initial fill and compatible with fleetguard filters for SCA maintenance. Will check pricing tomorrow.

As Paul404 suggested I bought Fleetguard Compleat 50, cost was less than the Castrol concentrate and didn't have to chase up demineralised water.
I put 40 litres in, level is in top tank of radiator but will need a bit more. I couldn't get a 0 unit filter so had to use a 4 unit filter.
